摘要
The Jiama polymetallic copper deposit is located in eastern Gangdise volcano-magmatic arc, which is an important component part of the Gangdise metallogenic belt. The Jiama deposit is a typical superlarge porphyry-skarn-epithermal polymetallic copper deposit related to post-collision. The combination of scanning electron microscope-cathodoluminescence（CL） and LA-ICP-MS microanalysis of Al, Ti, K and Fe in veined quartz has yielded results permitting a greater understanding of the complex mineralization of the Jiama porphyry-style deposit. The data obtained demonstrate the relationship between quartz precipitations, dissolution and ore deposition with the variation of ore-forming fluid through time.
